SOLVED CPANEL-36050 - Backblaze B2: Backup transport errors

phil99 · Feb 26, 2021

We have occasional problems when uploading to Backblaze B2, with backups failing to upload.

There are errors in cpbackup_transporter.log like the following example (actual account name has been replaced with "accountx"):

Code:

[2021-02-23 05:03:19 +0000] info [cpbackup_transporter] Uploading account backup /backup_cpanel/2021-02-23/accounts/account1.tar.gz to backup_cpanel/2021-02-23/accounts/account1.tar.gz (from 2021-02-23/accounts/account1.tar.gz)

[Lots more perl stuff snipped]

The backup software then immediately tries twice more:

Code:

[2021-02-23 05:03:19 +0000] info [cpbackup_transporter] Upload attempt #2 starting for /backup_cpanel/2021-02-23/accounts/account1.tar.gz to backup_cpanel/2021-02-23/accounts/account1.tar.gz for destination:  Backblaze B2

After failing for a third time, it gives up and immediately moves onto the next account:

Code:

[2021-02-23 05:03:19 +0000] info [cpbackup_transporter] Upload attempt #1 starting for /backup_cpanel/2021-02-23/accounts/account2.tar.gz to backup_cpanel/2021-02-23/accounts/account2.tar.gz for destination:  Backblaze B2

This carries on with a number of accounts failing to upload until there is a successful upload attempt 3 seconds later:

Code:

[2021-02-23 05:03:22 +0000] info [cpbackup_transporter] Upload attempt #1 starting for /backup_cpanel/2021-02-23/accounts/account3.tar.gz to backup_cpanel/2021-02-23/accounts/account3.tar.gz for destination:  Backblaze B2
[2021-02-23 05:03:25 +0000] info [cpbackup_transporter] Successful transfer of /backup_cpanel/2021-02-23/accounts/account3.tar.gz to backup_cpanel/2021-02-23/accounts/account3.tar.gz for destination Backblaze B2

I'm assuming the "error: CODE :500" is the error code received from Backblaze. If so, then according to the Backblaze blog post below [1], an error code of 500 is to be expected. If the application receives an error 500 code, it should immediately try again after getting a new url. However, if it gets another 500 code, it should wait a few seconds before trying again. It would appear that the WHM backup software is not doing this. This has resulted in the failure to upload a number of accounts.

Hey there! Thanks for bringing this to my attention. I've created case CPANEL-36050 to have our developer explore the possibility of introducing a delay in the Backblaze upload settings when an error is encountered. I'm following along with that case and I'll make sure to post an update here as soon as I hear something.

Thanks Rex.

cPRex · Feb 26, 2021

Sure thing!

cPRex · Apr 7, 2021

Update - we have a fix for this that will be included in version 96 when this gets released :D

phil99 · Apr 7, 2021

Great, thanks.

Sorry, but still seeing this error in version v.96.0.9. Should be pausing for a few seconds after failure #2, but that's not happening.

First few backups upload with no problem, and then B2 get's busy and the script does not pause.

Here's an excerpt from my logs/transport_errors.txt

OP here. We also continued to see this. A cPanel Analyst has recently been working on our system and think they have identified a fix. There is a support article you can follow, but I'm not sure if I can link to this. May be cPRex can add more detail.

Hello phil99. Would you mind providing the ticket ID so that we can review the resolution information that was provided in the ticket?

Hi, ticket #94327364.

dmart1n · Jun 11, 2021

I am also seeing issues with Backblaze offsite backups since Version 96.0.9

The problems I am seeing are:

1. When transferring files, it is no longer creating a new folder on Backblaze

It now always uses the same folder 2021-05-29/ and overwrites the backup from the day before.

It should create a new folder for each day - 2021-06-09 etc.

2021-06-09 is being saved to 2021-05-29/

There was a case filed on this. More information on this case can be found here:

cPRex · Jun 15, 2021

Update - the fix is scheduled to be included in version 96.0.11.

dmart1n · Jun 17, 2021

Hi

All our servers have all been upgraded to 96.0.11

The path creation issues seems to be resolved as the path is being created.

The backups are not working due to the following error

[2021-06-16 23:23:47 +0100] info [cpbackup_transporter] Upload attempt #1 starting for /backup/2021-06-16/accounts/[hidden].tar.gz to 2021-06-16/accounts/[hidden].tar.gz for destination: Backblaze Backups

The servers are all crashing as a result and I have had to disable the offsite backups to Backblaze

Can you review and provide a solution?

Thanks

cPRex · Jun 17, 2021

@dmart1n - could you submit a ticket to our team so we can check this on one of your affected machines?

pyrographics · Jun 24, 2021

I'm in the same boat as dmart1n with exactly the same errors affecting at least two of my servers, I have a ticket open #94335602

cPRex · Jun 24, 2021

Our team has opened case CPANEL-37482 to track the issue on new tickets as this seems to be happening again after it was recently fixed. You'll be getting a reply to the ticket saying something similar most likely, but we are aware of the issue.

MindServer · Jul 1, 2021

Hi,

I have the version 94.0.12 and have the same problem: WHM/cPanel not finalize sending the backups to remote server:

Unable to send “/backup/2021-07-01/accounts/account71.tar.gz to destination "backup-server"

Unable to send “/backup/2021-07-01/accounts/account72.tar.gz to destination "backup-server"

Unable to send “/backup/2021-07-01/accounts/account73.tar.gz to destination "backup-server"

Unable to send “/backup/2021-07-01/accounts/account74.tar.gz to destination "backup-server"

Thank you very much. Have a nice day.

cPRex · Jul 1, 2021

@MindServer - we aren't expecting the issue to be resolved on version 94. The case mentioned above is still being investigated at this time.
